Leakproof Thigh Savers help your teen get ready for anything without the worry of thigh chafe, leaks and sweat. 

They’re the perfect sidekick for skirts, dresses, uniforms and act great as a barrier between skin and the elements (like that hot leather seat or their raw denim shorts).

That’s up to them and their flow! Thigh Savers absorb about 3 regular tampons worth of period blood and are fit for light to medium days. On heavier days, your teen can feel most confident wearing them as a backup. 

That’s up to them! Lots of Knix customers love to wear Thigh Savers as underwear.

Just like regular underwear! Machine wash cold and lay flat to dry. Don’t bleach, iron or dry clean.

Leakproof Thigh Saver 6"

I thought I already submitted a review for this product. Everything good on product except waistband. They slide down. Waistband too loose. Perhaps I need xxx3 instead of xxxx4 with this particular product?

Love them!

I bought these for under summer dresses but honestly, they became my fav shorts. I love sleeping in them or just lounging around on a lazy day. They have a light coverage which is nice and they are breathable so you don’t get sweaty or overheated in them.
